ok i get asked numerous times what the top speed is of my scoob, and tbh i dont know so just say "about 160"

so what is the top speed of a STD 07 hawk STI?

is it limited?

what runs out first, gearing or bhp?

and no, i havent been close to finding out!!

 

These cars will make 150mph but they aint designed for that as in Japan the limit is 120mph. I am pretty sure that after 120mph the aerodynamics cause the intercooler scoop starts to become less effective and then inlet temps rise.......

Prolonged high speeds can lead to engine failure

 

Top speed is around the 150MPH mark, 154 i think.
It is supposed to be limited 155MPH.
The hawk sti is geared to around 200MPH.

For road, it doesn't matter what the top speed is, it's how it gets their that counts lol.

 

Geared for over 200 !!!!!!

REALLY ?????

 

I always just say 70 MPH when anyone asks me.

 

No

Its gearing is similar to that of a 2ltr UK car afaik, it doesnt redline as high so gives it similar theoretical top end of around 180ish mph.

I heard that it was geared for over 200MPH on here and just checked it now.
2.5 UK STi 6TH GEAR RATIO: 0.707
Tyre size is 225/45/17
Final drive for 2006-2007 6MT:3.545
Rev limit:7250

I used a top speed calculator and it came out with 214MPH.

 

i have a standard hawk 07 sti and did the clock on it 160

 

on an old runway that i had acess to before any one thinks i would be stupid enough to do it on the road, revs were still going but very slowly dnt think she would go too much more

 

LOL won't get there of course, aero of a brick!

TX.

Edit - fyi my old 450hp classic topped out at a true 159mph, Marham RAF base.

 

That means at the 155mph limiter you will be doing about 4500rpm, not going to happen

Tony

 

At what rpm?

Tony

 

ive been in a 350bhp twin scroll not me driving, 163 sat nav

 

Now that you put it like that, it does sound wrong, but all the figures are in check.

 

Ive seen 155mph in my RB320 and it was still climbing. I read about a standard RB cloicked at 170mph on an autobahn.
I worked the gearing out at 183.4 mph at the redline in 6th gear.

 

Think you've miscalculated somewhere, mine used to do 215MPH

 

100000mph! lol that enough!! lol

 

I hope so

 

You probably had a higher rev limit lol

 

think you might find the hawk box will do a little more than 180mph.mine will go just past 160 in 5th on the clock.i have never had mine to its full rpm in 6th,nor would i want to.my speedo only reads 160 so i carnt really say what top speed i have done but the needle has been right down the bottom into the digital bit and the car was nowhere near the redline.i'd say if you wanted to hold it in 6th gear, that it would probably do 200mph.

 

my sti hawkeye does 200mph with a six speed box but that speed goes down to 190mph in the twisties

 

How many Imprezas have you heard of running 200mph+ ???
Not many...

I'm sorry but no standard Impreza will get anywhere near 200mph, the speedo may read 180 odd but I would hazard a guess it's far from accurate.

 

I have a standard 2006 hawk sti, and had the opportunity to test it on some private land.

Speed is electrically limted at 160mph at around 5900rpm, it will not go off the clock as hits fuel cut. id say it'd be good for at least 180-190 on standard rev limit which is just a tad over 7k rpm.

As mentioned its a rally car and is designed to get there not stay there.

 

was about 6 i think still had a bit more to go

 

no a standered one wont because it will hit the saftey limiter.my speedo is approx 5 mph fast according to the sat nav.

 

FFS look at the scoob top speeds from the 30-130 days, no where near fookin 200mph & most are well modded cars not standard

TX.

 

I wouldn't think there are many what so ever John that would do a true 200+ do you?

 

What sort of speeds were Imprezas getting to at TOTB top speed run ??

 

My owners manual says 154MPH...so thats what i tell people. I have honestly never tried to prove it right or wrong. So i just quote the book figure.

Same with Prodrive's claimed 0-60 time of 4.6 seconds...never wanted to wreck my cars transmission to see if its accurate.

 

194.1 standing 1Km not maximum speed obtainable though
